Abstract
A method of producing an ink-jet recording head using ion milling is provided. The method includes the steps of forming a piezoelectric layer subsequent to an electrode layer on a substrate by using a thin-film deposition technology, forming an energy-generating element for generating energy for ink ejection by etching the electrode layer and the piezoelectric layer simultaneously by ion milling, and removing a fence formed by deposits of mixed fine powders including those etched off the electrode layer and the piezoelectric layer.
